The monument comprises the remains of a drystone ring fort of later prehistoric date surviving as a ruined structure.

The monument forms one of a group of four ring forts in this part of Glen Lyon. It lies on flat, low-lying ground on the N bank of the River Lyon. The overall diameter of the structure is approximately 23m with walls up to approximately 4m wide. The interior is occupied by at least two substantial rectangular buildings which appear to be secondary constructions. Although classed as a ring fort it appears more likely to represent a primarily domestic building of the later prehistoric period.

The area to be scheduled encompasses the visible features and an area around them in which traces of associated activity may be expected to survive. It is sub-circular with a maximum diameter of 55m as marked

in red on the accompanying map.
